Actually, not true for ABS. ABS looks at changes in the rate of deceleration of each wheel individually, not differences in speed of one wheel relative to another. (Although one or more wheels turning at a speed significantly different than the rest will likely trigger the diagnostics to indicate a sensor problem.)

DSC and TCS do, of course, look at wheel speeds relative to each other.
